To all whom it may concern.-

Be it known that we, ARCHIE O. HAYES and EDWARD O. HEMPHILL, residing at Los Angeles, in the county of Los Angeles andState 5 of California, have invented new and useful Improvements in Perforating Attachments for Printing-Presses, of which the following is a specification. 7

Our invention relates to devices for per' 10 forating order-blanks, sales-slips, and other papers, whereby the samemay be detachably bound together or removably placed on files;

and the objects thereof are to provide a simple perforating device which can be used on t 5 any printing-pressto perforate the paper at the same time that the paper is being printed on and to collect and hold the punched waste disks and prevent them from being scattered around and creating a nuisance. We accomzo plish these objects by. the device described herein and illustrated in the accompanying drawings, forming a part hereof, in which- Figure l is a perspective View of a portion of a printing-press with our perforating det 5 Vice mounted thereon. Fig. 2 is a plan view of our' magazine for holding the punched waste disks of paper, on which are adjustably Fig. 3 is an enlarged cross-section of our magazine on the line 3 3 of Fig. 2. Fig. 4 isa perspective view of the nut D, into which the shank of the punch is screwed. Fig. 5 is a top and edge view of the metal disk. which the punch impinges when perforating the paper.

A is a drawing of our magazine, in form preferably a long narrow box, with a longitudinal opening B in the top near one side thereof and is adapted to be used in the chase or type-form as a piece of furniture to receive and hold the waste paper disks as they drop through the punch. O is the hollow perforating-punch, which has a bore through which the punched waste disks pass into the magazine and also has a {threaded shank adapted to pass through slot B and be screwed into nut D to clamp and hold the punch in any desired position on the magizine. By

providing nut D with supporting-legs D, (shown in Fig. 3,) adapted to rest on the bottom of the magazine and sustain any downward thrust when perforations are being made in the paper, the top and sides of the magazine may be made of very light material. As many perforating-punches may be placed on .the magazine as desired. The magazine is placed in the type-form or chase E on the press F and locked therein, with the perforatingpunches clamped in position to make the desired perforations. The magazine, with the punches thereon, is of such height that the top or cutting edge of the punchlies a little below the top or face of the type, so asnot to contact with the ink-roller. On the tympan-sheet G, being the sheet next to the top sheet, we attach, preferably by waxor paste, 6 as many small disks H of soft metal, preferably copper, as there are perforating-punches and a little larger than thecutting edge thereof, so as to register with the punches to make a clear-cut perforation in the paper. These disks are preferably provided with a slight rounded projection H on the face thereof to force the central part ofthe disks farther into the bore of the punch than the edges to prevent the disksfrom comingout of the punch at the cutting endthereof. When the punchesare in position, a narrow piece of cardboard, perforated with holes which register with the holes in the punches, is slipped along the slotin the magazine to close the opening in the magazine to retain the punched waste disks therein until it is desired to remove them.

By the foregoing construction a cheap and efficient perforating device is provided which can readily be attached to and used on a cylinder-press as well as on a job-press. The magazine will retain a large number of the punched waste disks and thereby prevent them from getting into undesirable positions 0 and becoming a nuisance.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A perforating attachment for printingpresses, comprising a magazine with a longitudinal opening therein, to hold the punched waste paper disks, adapted to be fastened in the chase; a slot in said magazine along the top to permit the passage therethrough of the threaded shank of the punch; a threaded nut in the magazine to receive and engage the shank of the punch, and to securely hold the punch in any desired position; legs on said nut arranged to rest on the bottom of said opening and rigidly support the punch while being operated; a disk in place on the tympan-sheet and arranged thereon to register with the punch.

2. In a device for perforating paper, while printing is being done on the paper, the perforating-punch O adjustably mounted on a disk receiving and holding chamber immediately undersaid punches, and connecting directly with the openings therein, and a disk receiving and holding chamber.

3. In a printing-press provided with a magazine having hollow punches, the herein-described disks H, mounted on tympan-sheet and having a central portion to crowd the center of the waste disk farther into the punch than the edges thereof, substantially as and for the uses herein described.

4C. In a printing-press, having a perforating attachment, the herein-described punch 0, having a hollow central opening therethrough, in combination with the disk H on the tympan-sheet of the press, and so disposed thereon as to register with the punch on the type-form when the press is being operated; the said disk having a central projecting portion to crowd the center of the waste paper disk farther into the opening in the punch than the edges.

5. In a printing-press, the herein-described magazine provided with an opening to receive and hold the waste paper disks cut from the paper, adapted to be fastened in the chase; hollow dies movable along said opening; and a plurality of disks on the tympan-sheet adapted to register with the dies on the typet'orm, when the press is being operated, substantially as shown and described.

In witness that we claim the foregoing we have hereunto subscribed our names this 26th day of October, 1900.
